Our own code is IPv6 friendly, but for parts of our test we rely on the OpenSSL tools, which are still IPv4 only. Engineering around the OpenSSL tools is on our todo list, but it's not a trivial task. Practically speaking, I think we will support IPv6 in the next version of the testing tool (now in development).

As for the schedule, here's what I can offer: we are currently migrating the server to a new facility, where we will have IPv6 connectivity (we don't now). Soon after that the work-in-progress of the v2 of the test will be announced. It will include IPv6 support from the start.
